Working pretty well so far!
The game hangs occasionally, I'm not sure if that's expected to happen or not, though for the purposes of testing smaller arena fights it shouldn't be a huge issue.
The units overview is pretty helpful too. It let me spot a kick attacked with a foot of some 40 urists in weight and with the wrong tissue layer as well as some oddities in the weapon-bodypart (low contact area, etc) the armor man creature has.
I'll be tinkering around with this as well as my armor man creature, I'll have some more feedback eventually.
The hanging is expected. I go to disk often to write that log file, so the disk writes are killers. I could have made the user issue a flush command, and that would have been faster, but in the end, I decided on the most non-intrusive design.
The biggest reason why you see it hang up, is that the first time a creature does an attack, it dumps a bunch of static info about that creature once. This is the stuff you see in the units tab. The older versions used to stream all of that data for every attack. It is a little more disk friendly now, but you will still have a little noticeable lag, when I'm dumping the creature info.
I am so happy that you are finding it useful
